WATER-CLOSET BOWL.

SPECIFICATION formingpart of Letters Patent No. 721,786, dated. March 3,1903.

Application filed May 28, 1901. Serial No. 62,202. (No model.) I

To all whom it may concern:

Be it known that 1, JAMES J. DONOVAN, a citizen of the United States,and a resident of Peekskill, in the county of Westchester and State ofNew York, haveinvented certain new and useful Improvements inWater-Closet Bowls, of which the following is a specificatio Thisinvention relates to watercloset ventilation, having referenceparticularly to the attachment of an air-exhaust pipe directly to thecloset-bowl. Its object is to afiord an efficient means for theconnection of the ventilating-pipe and a part of the devices employedfor startingthe ventilating appliances into action.

The objects are attained by the means set forth in this specificationand the accompanying drawings.

Figure I of the drawings shows the closetbowl inelevation. Fig. II is atop View of the closet-bowl. Fig. III is a vertical crosssection of thebowl through line 10 of Fig. I. Fig. IV represents a section of thebowl, showing the manner of making connections with the bowl. tion ofthe top of the bowl to which the devices employed in ventilating it areattached. Fig. VI is an enlarged detail showing a connection with thebowl.

The closet bowl represented is what is known as a siphon-jet closet,upon which the seat is secured by means of hinge parts in the holes Z Z,Fig. II, a top View of the posts and hinges being shown in Fig. V, ffrepresenting the posts, g g the hinges for the seat, and g g the hingesfor the seat-cover. A post is shown also in Fig. IV, it being held inplace by a nut under the flange b of the bowl a. In Fig. II one of thehinge-posts is shown to be just above a channel e through the bowl, andwhen this structure occurs the nut for the post would be within the saidchannel.

As already stated, this invention relates to particular methods ofventilating water-010s etssuch, for instance, as the employment of a fanto be driven by the Water that fills the flushing-tank for Washing outthe closet, the fan having a connection from its intake or its brancheswith the interior of the bowl, or of any method of Ventilating thatincludes Fig. V is a view of that por such direct connection with thebowl. The closet-bowl herein illustrated is not claimed as in any mannernew, except as to the means herein described for adapting it to the saidmanner of ventilating it. The means are shown in plan in Fig. II. Thehole d represents the usual opening for the flushingpipe connection, theconnection being shown in elevationin Fig. IV and in plan in Fig.V. At.d, Fig. II, a like opening is shown for a ventilating-pipe connection,which is similar in size and construction to the flushing connection asshown in plan in Fig. V. The flushing-opening d has two channels leadingfrom it to the interior of the bowl, one (represented'by the brokenlines 72) that leads to a perforated channel 1, Fig. III, around theinside of the rim of the bowl, said channel and perforations 2, Fig.III, being shown in crosssection in Fig. III. The other channel(represented by broken lines '5) leads to the jetopenings j at theentrance to the bowl-trap, as in Figs. II and III. The opening (1 has achannel connection with the interior of the bowl, as shown by the brokenlines e e, the

outlet within the bowl having an area corresponding with theventilating-pipe to be used and entering the bowl below theflushing-rim, as shown at m, Fig. III. The course of this channel isalso shown in Fig. I by broken lines e. When the ventilating-fan is inmotion, there will be a movement'of air into the bowl through its topand out of the bowl through the inlet m.

When used with a ventilating system that is operated by Water caused toflow by the depressing of the seat on the bowl, ball mechanism isrequired to transmit the movement of the seat to the valve that afiordsthe water-supply. To facilitate the attachment of this lever, a lugcisadded to the side of the closet-bowl, as shown in plan in Figs. II and Vand'in cross-section in Figs. III and VI. The lug is provided witha-hole n for the insertion of a stud for supporting a lever, as shown inFigs. IV and VI. In Figs. II, III, and V this lug is shown to have itstop flush with the surface of the bowl. In Fig. IV the top of the holeis shown to be recessed, as at s. In Fig. VI the lug is set below thesurface of the bowl. Fig. IV represents a stud p for the attachment of alever suspended from the lug, the securing-nut '1 having its top flushwith the top surface of the lug. The same stud applied to the lug, shownin Fig. III would cause the nut r to be above the top surface of thelug. The stud, however, may be reversed in each of these figures, sothat the eye 7* would be above the lug 0 instead of hanging below it. Asshown in Fig. VI, the stud may be applied with the eye above the lug,and the top of thelug and thelever would be flush with the surface ofthe bowl or may be made to be below the surface of the bowl. In thisfigure the hole at is shown to be recessed on each side to receivecushioningwashers 8 8. The stud 3 has a shoulder 5 on The lever 7 beingequally distant from the center of the bowl, and a lug on one side ofthe bowl for valve-operating mechanism, substantially as herein shownand described.
